## Summary description

CBO BlueOptics QSFP28 3m Male/Male 100Gbit/s is a 3-meter QSFP28 optical cable designed for 100 Gbit/s high-speed data transmission. With male QSFP28 connectors on both ends, it connects compatible switches, routers and servers in data centers and high-performance networks. Ideal for short-reach links, it provides reliable low-latency connectivity and straightforward plug-and-play installation.

## Long description

The CBO QSFP28 100Gbit/s BlueOptics 3m Male-to-Male optical cable is a 3-meter direct-attach cable designed for high-density, short-reach 100 Gbit/s links. With male QSFP28 connectors on both ends it supports direct connections between compatible switches, routers and servers in data centre and enterprise network environments. The cable provides a compact, low-latency physical connection that is suitable for top-of-rack, aggregation and computing cluster applications where space and signal integrity are important.
Advantages
This BlueOptics QSFP28 cable offers a reliable, single-segment solution for 100 Gbit/s links without the need for separate transceivers. The fixed-length 3 m design reduces insertion points and potential signal loss compared with patchcord-plus-transceiver options. Male QSFP28 connectors ensure compatibility with equipment that accepts QSFP28 direct-attach cables, and the assembly supports plug-and-play installation for quick deployment. The cable's form factor and materials are optimized for high-density racks and constrained cable paths.
Suitable for
Short-reach interconnects between switches and routers in data centres
Direct server-to-switch connections in high-performance computing clusters
Top-of-rack and aggregation layer links where 100 Gbit/s throughput is required
Environments that require low latency and compact cabling
Key specifications
Interface: QSFP28 male to QSFP28 male
Data rate: 100 Gbit/s
Length: 3 meters
Signal type: Optical direct-attach cable for short-reach links
Connector gender: male on both ends
Use case: Direct-attach, fixed-length cable for high-density installations
How to use
Ensure both endpoints support QSFP28 direct-attach cables and are powered down or follow hot-plug procedures recommended by the equipment vendor. Align each male QSFP28 connector with the corresponding port and insert until it seats firmly; observe any port latching mechanism if present. After insertion, verify link status via the connected devices' management interfaces. For removal, release the latch and extract the connector straight out to avoid bending or stressing the cable. Do not route the cable through sharp bends and avoid excessive pulling force to maintain optical performance.
Usage recommendations
Install the cable in rack layouts that avoid tight bends and maintain manufacturer-recommended bend radii. Keep mating surfaces clean and protect connectors from dust when not in use. Use this 3 m QSFP28 cable for short interconnects inside racks or between adjacent racks rather than long-span backbone links.
